.FUNITED STATES IPATJENTDFFICEQ Joni: kALwonA. or CUBA, Kansas.

To all whom it may concern:

Be it known that I, JOHN KALIvonA, a citizen of the United States ofAmerica, residing at Cuba, in the county of Republic and State ofKansas, have invented new and useful Improvements in Scrapers, of whichthe following is a specification.

This invention relates to a scraper and has for its primary object theprovision of a scraper in which the scraping element may be quicklythrown to an operative or inoperative position by the driver changinghis position upon the platform.

An object of the invention is the novel manner of mounting andpositioning the roller so that the scraper may be properly guided andthe tendency of the latter to turn the scraper overcome. I

Besides the above my invention is distinguished in the use of a roller.arranged directly behind the scraper so that the ground may be rolledafter the scraping operation and besides when found convenient theplatform may be overbalanccd for moving the scraper out of engagementwith the earth.

With these and other objects in view the invention will be betterunderstood from the following detailed description taken inconnectionwith the accompanying drawing, wherein Figure 1 is a top plan View ofthe scraper.

Fig. 2 is a side elevation. V

Fig. 3 is a longitudinal, sectional view.

Fig. 4 is a bottom plan view.

Again referring to the drawings illustrat ing one of the many formsinwhich the in vention may be constructed, the numeral 1 designates aplatform reinforced by the metal frame 2. This frame 2 has dependingbearings 3 and at the front has secured thereto hooks 4: by means ofwhich the scraper may be drawn. At the front of the platform I arrange ascraper blade 5extending at an angle to the direction of travel of thescraper when in use so as to convey and deposit the earth to one side ofthe road. By arranging the blade at an angle which is absolutelynecessary in an apparatus of this character there is a tendency for thescraper to move to one side of its line of travel owing to the angle ofpressure between the scraper blade and the earth. To compensatefor thisaction and besides to accomplish another beneficial effect I provide aroller 6. This roller 6 is of a length Application filed September 26,1919. Serial No.'326,423.'-

approximately equal to' the width of the platform and is arrangeddirectly behind the scraper so that after the scraper has performed itsfunction the roller will press the earth into a solid mass. The angularpositionof the roller is such that it tends to move the scraper in adirection opposite to the action of the scraper blade and therefore 7the scraper is properly kept in its line of travel. The angular positionof the roller may be readily changed by adjusting the screws 7 thatbindagainst the adjustable bearings 8 which are slidable within thebearings 3. To complete the invention I I have formed an opening 9 inthe top of the platform so that access may be had to the roller forcleaning the same. By referring to Fig. 1 of the drawings it will beseen that the shaft 10' of the roller extends beyond the bearings so asto have attached thereto wheels 11 in case the condition of the roadmakes it necessary to relieve the roller of a portion of the weightthereon.

From the foregoing description taken in connection with the accompanyingdrawing it should be apparent that I provide an apparatus of simplesubstantial construction in which the parts are so related that thedriver upon changing hisposition upon the platform may tilt thellatterin a direction to throw the blade out of engagement with the road. I

It'is of course to be understood that the invention may be constructedin various other manners and the parts associated in other relation andtherefore I do not desire to be limited in anymanner except as set forthin the claims hereunto appended;

What I claim is 1. A road scraper comprising a platform, elongatedbearing members disposed upon the underside thereof at its edges, alaterally inclined blade carriedat one end of the platform, bearingblocks slidably adjustable one end, a single roller extending at anangle transversely of the platform, and a device for changing theangular position of the roller with respect to the blade, whereby to 4.A road scraper comprising a'platform, counteract the tendency of thedevice to a scraper blade secured to the front edge'of move laterally.:the plat-form' at'anangle to the direction of 3. A road scrapercomprising a platform, travel of the scraper, a roller ofa length 5 ascraper supported at an incline to the approximately equal to the Widthof the 15 direction of travel of the scraper, a roller platform andmeans for adjusting one of the mounted under the "platform with one ofits bearings of the roller so that the angular bearings adjustable sothat-the angular posiposition thereof may be changed at will; tion ofthe roller with relation to the blade In testimony whereof I aflixmysignature.
